Bridge over a local road and brook
Večeřa, Jan ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The Diploma thesis deals with the design of the bridge construction that conveys the road I/11 across the Bystry brook and the local road between Nebory and Oldřichovice. The construction is designed in four options, one of which was selected is the variation of the prestressed onebeam construction of four fields and the lenght of bridging 106,6 m. Calculation of the effects of the load is carried by a computer program Scia Engineer. Assessing the design is done in accordance with applicable European standards EN 1992-1-1. It is also elaborated well arranged drawing documentation, construction process and visualization of the bridge.

Bridge on a motorway
Lindtner, Tomáš ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
The subject of Diploma’s thesis is the design of a road bridge on the R1 expressway, at km 1,293 above the road III/51311. The main content is static calculation of supporting structure consisting of four spans. Four studies were processed and the first variant of double-girder monolithic structure was chosen. The range of spans is ranging from 25 m - 30 m. Double-girder consists of two post-tensioned concrete beams and reinforced concrete slab. Static models and load effects are solved in Scia Engineer. Bridge is located in the horizontal curvature, however, compromise was elected (because of small curvature), assessing the upright design. Calculation is made without effects of temperature, wind loads and horizontal forces causing by traffic.

Bridge crossing over Svitava river and railway track in Blansko
Smělíková, Petra ; Konečný, Vojtěch (referee) ; Křižan, Lukáš (advisor)
The aim of the Diploma Thesis is elaboration of study of bridge crossing over the Svitava river and ČD railway track in Blansko. It concerns a five-pole steel beam road bridge with through-span which carries road of the third category. The static system of the construction is solved as solid-web beam of 1.3 meters height which is in three middle spans reinforced by truss construction with top chord and system of diagonals without verticals. The height of the main beam where reinforced by trusswork is 4.75 meters. The width of spans in the road axis is 18.5 + 30.525 + 44.4 + 30.525 + 18,5 metres. The bridge deck consists of steel cross beams bonded with reinforced concrete slab of 200 millimeters of thickness. The drive-through width of the roadway is 7.0 meters. The bridge is fitted with right-sided walkway placed on steel cantilevers. The walk-through width of the walkway is 3.0 meters. Material used is S355 Steel, C30/37 Concrete and S460 Steel which is used for marginal spans of the bridge. Load-bearing construction is assessed in compliance with current technical requirements laid down by European Directives, so called “Eurocodes”. The calculation of inner powers is performed using the Scia Engineer 2013.1 software.

Bridge on a ramp
Otevřel, Rostislav ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
Thesis describes the design and assessment of a plan view of a curved road bridge, which is a part of an elevated crossing transferring directional divided communication and tram line of public transport in Brno. There are four variants of cross sections designed, from which is selected bicameral cross section with arched angled bottom plate, which should be aesthetically pleasant to impress in an urban environment. Static calculation is processed and design is assessed by current European standards. Then clear and detailed drawings, the process of construction and visualization of the bridge are processed.

Bridge over the Olše river in Návsí
Mendroková, Magda ; Nečesal, Petr (referee) ; Marván, David (advisor)
The diploma thesis deals with design and assessment of steel arched bridge with the semi through bridge deck placed on the third-class road. This steel structure is drawn up to bridge water barrier – the river Olše in Návsí. The distance between axes lay on abutments is 48,5 meters. The bridge´s supporting structure consists of two steel arches angled towards each other and fastened to the foundation blocks. The supporting beam of the bridge deck is tied to the arch by tie-rods. The tie-rods are designed to the V-shaped system.

Bridge across the Morávka river at km 6.205
Hollý, Tomáš ; Marván, David (referee) ; Nečesal, Petr (advisor)
The subject of the thesis is to design and consider steel superstructure of a composite steel-concrete road bridge. It is a continuous beam with seven spans of 36,0 + 57,0 + 75,0 + 90,0 + 75,0 + 57,0 + 36,0 = 426 meters. The superstructure consists of welded I-beams, which pass into closed box girder. The calculations take into account the construction phase.

Prestressed road bridge in Staré Město
Juříček, Lukáš ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The thesis proposes the design of main structure concrete bridge,which is transferring highway road across the river Krupá in Staré Město.It is simple span bridge with length of 14,995 m.For the next calculation were chosen post tensioned concrete trapeizodal slab.The slab is assessment on serviceability limit state and ultimate limit state according to valid European standarts.

Prestressed road bridge in Staré Město
Krč, Rostislav ; Trenz, Jan (referee) ; Koláček, Jan (advisor)
The thesis focuses on design of superstructure of concrete bridge, which passes a roadway across the river Krupa in the town of Stare Mesto. It is a simple span structure with length of 19 meters. For further elaboration, post-tensioned concrete slab with trapezoidal-shaped cross section was chosen. Assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Furthermore, a design of post-tension according to former Czech technical standards (CSN) was studied. The thesis includes technical drawings and visualization.

Road bridge over the Trkmanka river in Velké Pavlovice
Coufal, Jakub ; Panáček, Josef (referee) ; Koláček, Jan (advisor)
The subject of this thesis is the design of the bridge constructino across the river Trkmanka in Velké Pavlovice. The supporting structure consists of a reinforced concrete slab on one field. The load was calculated in Scia Engineer software and compared with a simplified method of calculation of effective width. Static calculation was continued counted manually.
